Foodservice giant Sodexo has signed a franchise deal with sandwich chain Subway to introduce the high street brand to its retail offer.
Subway has been chosen to partner with Sodexo at high-volume sites with a variety of food outlets, such as universities, hospitals and military bases.
Sodexo has so far opened Subway franchises at Brunel University in London and Royal Sussex County Hospital in Brighton.
A third is expected to open at the Defence School of Transport, based at Normandy Barracks, Leconfield, East Yorkshire, in the autumn.
Michelle Hanson, commercial director at Sodexo UK and Ireland, said the company aims to offer its clients and customers as much choice as possible.
"We appreciate that people like the option of having high-street brands on site and the Subway brand is a good fit for us offering fast, freshly prepared sandwiches including healthier, low-fat options," she said. "This is very important to us because of our commitment to nutrition and wellbeing and promoting a healthy lifestyle for our employees, clients and customers."
Trevor Haynes, area development manager for the Subway brand UK & Ireland, added: "The simple operations, alongside minimal space and equipment requirements, mean that our stores are uniquely suited for a whole variety of sites.
"The Subway brand is keen to develop non-traditional locations in partnership with successful companies just like Sodexo. This form of growth will be an integral part of the franchise's development, overall expansion and on-going strategy over the next five years in the UK and Ireland."
